product-lifecycle skillA

product-lifecycle is agent-read markdown (skill) from magnus919/agent-skills: Route a product through its full lifecycle — discovery, strategy, portfolio choice, roadmap, UX and requirements, experimentation, delivery handoff, adoption, success, and lifecycle review — by composing existing specialist product skills with phase-entry evidence, handoff artifacts, and escalation rules. Use when evaluating a new product idea, managing a product through its lifecycle, or connecting product phases that currently operate in isolation. Do not use for a single product task that is .

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
